Hi everyone, over the last few months I seem to get quite breathless with little exertion. This is quite worrying and it seems the more I think about it the worse it gets. I mentioned this to my doctor the other day and he checked my chest and it sounded clear. In addition to this I had 2 types of lung function tests - one was Spirometry and the other a Peak Flow test. One in particular was used to diagnose Emphysema (I am a smoker who is trying to quit). Both results came back normal so why is it that I am still breathless? Have I got reason to worry so much about this? Has anyone else experienced the same? Thank you.
